: Are you familiar with natural gas lines that are used to hookup portable gas grills? My home has natural gas, so I am considering running a gas branch line (with shutoff) to the outside of my house (it will terminate just abouve ground level in the backyard). I have seen special flexible rubber hoses that connect this gas line to portable gas grills... thereby allowing the gas grill to run of my home's natural gas supply instead of the typical propane cylinders. Can you give me more information on how this hookup is installed, and where parts are sold? Thanks!
